Heather Locklear is dating Beverly Hills plastic surgeon Dr. Marc Mani, sources exclusively tell Page Six. The “Dynasty” actress, 51, who was previously married to Mötley Crüe drummer Tommy Lee and then Bon Jovi guitarist Richie Sambora, appears to have sworn off rock bad boys after getting close to dashing Mani, who appeared on TLC’s “Plastic Surgery Beverly Hills.” One source sniped, “He’s also helpful for getting some work done.” Reps for Locklear didn’t get back to us. Mani didn’t comment.
